I don’t use “heavy for caliber” bullets in anything, ie my 7mm-08. I think the Barnes TSX or TTSX needs to be lighter for caliber as mono’s tend to perform better with higher velocities and I can very safely get well over 3100 fps thus I shoot the 120 gr. in that type bullet. If shooting a cup’n core, it will be a 139/140 gr. The one exception would be the 120 gr. Ballistic Tip as it is tough enough to handle the velocity and still perform well. This holds true in other chamberings as well. My thinking is (and YOMM) that if I need a “heavy for caliber” bullet, then I need a heavier caliber! I have no need for the better BC that “HFC’s” yield because I don’t shoot beyond 300 yds. at the most. Just me.
